What it is Hareline UV Estaz is a UV mylar chenille built on a core-wrapped construction with UV-enhanced mylar fibers. It makes a translucent, light-reflective body with strong UV flash, and it stays durable and bulky once you wrap it. In the water it gives you a full profile with lively movement from those fibers. What to tie with it Wrap it as a body material on streamers, nymphs, steelhead flies, blobs, and estaz-style eggs, either as the main body or as a hot spot section. Most tyers tie it in by the core and palmer it forward in touching turns, then brush or pick it out to open up the fibers and build even more volume. It also works well when you want a quick, consistent “rope” body without having to dub. Flies and the fish they're for UV Estaz is right at home in egg patterns fished for trout and steelhead in rivers, especially when you want that translucent, glowing egg look with some extra UV kick. It’s also a common body choice on steelhead patterns swung or dead-drifted for migrating fish, where the bulk and flash help the fly show up in colored or broken water. On blobs and other attractor-style bodies it’s a go-to for stocked rainbows in stillwaters and ponds, where that bright, full chenille profile triggers reaction takes.
